lUNiTEn STATES PATENT iiIlLTON N. RANKINS, OF VILLETTSVILLE, OHIO.

CANTHOOK.

SPECIFICATION forming part of Letters Patent No. 392,752, dated November 13, 1888.

Application filed July Q1, 1888. Serial No. 280,626. (No model.)

To all when?, 'it may concern:

Be it known that l, MILTON N nLsoN RAN- KINS, ol' iVillett-sville, in the county of Highland and State of Ohio, have invented a new and useful Improvement in Oant- Hooks, of which the following` is a full, clear, and exact description.

This invention relates to cant-hooks for rolling logs or turning heavy pieces of timber; and it consists in a certain articulated construction and novel combination of parts, substantially as hereinafter described, and pointed out in the claim, whereby a very [irin hold, iree from slip, is secured for the hook on the log or b ody to be rolled or turned, and a powerful action is obtained for the cant-hook.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure 1 represents a side elevation of my improved cant-hook as applied to the rolling of a log; and Fig. 2, a horizontal section of the implement upon the line xn: in Fig. l, looking upward.

A indicates the handle or lever of the implement, and Bits hook proper. This hook B is double-pivoted, rst, as at I), to the lower end of a strap, C,which is jointed or pivoted above, as at c, to the lever or handle A, near the forward end of the latter, and, secondly, as at d, above the pivot?) to the rear end of an articulated bar, l) D', having` its sections pivoted together, as at c, and its forward section, D, pivoted or fulcrumed, as at f, to the front end por* tion of the lever A, as by an eyebolt, g. By this articulated construction of the cant-hook,

when the implement is placed in position on a log, G,with the hook proper, B, hanging downward, a slight upward movement ofthe lever A from the rear will bring the point of said hook up to the log and fasten it therein, so that it will be impossible for it to give Way or slip, and the greater the upward pressure that is exerted on the lever the iirmer will be the hold. The main or acting fulcrum of the lever will be atf, and the lifting-point of the hook through the strap or connection O be at c; but the articulated bar or connection D D will be brought beneath its pivots cf down on or over the log, andthe tendency to iiex said jointed or articulated connection D D as the lever or handle is Worked to turn or roll the log will exert a backward thrust on the pivot d of the hook, which will exert a tendency to turn the hool; on its pivot Z and cause the point ofthe hook to sink deeper or iirnier into the log` and the articulated connection D D to bear down securely on the log.

Having thus described my invent:iou,what l. claim as new, and desire to secure by Letters Patent, is

The combination of the lever or handle A, the hook proper, B, the link or connection C between said handle and said hook, the pivots Z) d, and the articulated bar or connection D D', l'ulcruined or pivoted to the lever, as at f, and having its sections jointed or pivoted together, as at c, back of the fulcruni or pivot f, substantially as shown and described.
